Patna, Aug 20 : Unidentified gunmen have indiscriminately fired at a restaurant in Bihar's Muzaffarpur district. The assailants came on motor bikes and fired on the restaurant. Some of the bullets hit the window panes. A video of the incidents has also gone viral on social media. Some customers are seen taking dinner meals inside the restaurant and immediately protect themselves by crawling under tables to avoid coming into the firing range. However, no one was dead or injured during the incident. It is believed that the accused committed the crime to extort money from the restaurant owner. 'As soon as we came to know about the firing incident, we deputed a team of Sadar police station. Around 10 rounds were fired at the restaurant.
